On the other hand, datagram sockets are connectionless. Calling -.BR connect (2) +.MR connect 2 on a datagram socket merely sets the peer address for outgoing datagrams sent with -.BR write (2) +.MR write 2 or -.BR recv (2). +.MR recv 2 . The caller of -.BR connect (2) +.MR connect 2 can use .BR getpeername () to obtain the peer address that it earlier set for the socket. However, the peer socket is unaware of this information, and calling .BR getpeername () on the peer socket will return no useful information (unless a -.BR connect (2) +.MR connect 2 call was also executed on the peer). Note also that the receiver of a datagram can obtain the address of the sender when using -.BR recvfrom (2). +.MR recvfrom 2 . .SH SEE ALSO -.BR accept (2), -.BR bind (2), -.BR getsockname (2), -.BR ip (7), -.BR socket (7), -.BR unix (7) +.MR accept 2 , +.MR bind 2 , +.MR getsockname 2 , +.MR ip 7 , +.MR socket 7 , +.MR unix 7 |
